android 播放assets mp4,android - How to play a video (.mp4) from assets or raw folder with the video i...

How can i play a mp4 video from my assets or raw folder with the video intent?

whatever i try i always get :

06-25 14:32:14.070: E/AndroidRuntime(3070): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=android.resource://mypackage/raw/myvideo }

I tryed:

Intent tostart = new Intent(Intent.ACTION_VIEW);

String movieUrl = "file:///android_asset/myvideo.mp4";

// String movieUrl = "android.resource://" + getPackageName() + "/raw/" + "myvideo.mp4";

tostart.setDataAndType(Uri.parse(movieUrl), "video/*");

startActivity(tostart);

I can only find answers where people use video's from SD's card, is there any option so i can use the raw or assets folder?
